Pokemon X and Y will be released all around the world for 3DS in October 2013. The main Pokemon adventures are always released first in Japan and we often have to wait many months for Pokemon games to be released in the UK. For example, Pokemon Black And White 2 were released in June 2012 in Japan but we had to wait until October for them to come to the UK.
During the first Pokemon Direct, Nintendo President Satoru Iwata said: "As indicated by the long history of the Pokemon series, there are a large number of Pokemon found in the games and a significant amount of resources are required for localisation. Our challenge has always been how can we deliver Pokemon games to people across the world at the same time while ensuring that the the quality remains high. With this release we've been able to overcome this challenge. This means you'll be able to enjoy the adventures with Pokemon trainers everywhere this October."
